Fig. 7 is a detail showing the operating mechanism used in Figs. 5 and6.

This invention comprises a ring or its equivalent pivotally mounted onits periphery so that it may oscillate on this pivot. Inside the ring astud or equivalent is provided to engage the inner perimeter of thering. The stud and the pivot are movable relative to each other so thatas the stud is moved away from the pivot a distance corresponding to thediameter of the ring, the ring is rotated until this position is reachedby the engagement of the stud with the ring. At this point, if the studis brought closer to the pivot the ring is freed and can move to aposition where it is stopped by the stud again engaging the ring.

The ring may be provided with some form of translating device orindicator which provides momentumto the ring so that when the .studiismovedfrom theiinner to the outerpos'ition-itengages the perimeter of thering, causing itlto rotateto the position .wherelthe stud .is separatedfrom thepivot a distance corresponding to the diameter of thering..Atthis pointif ,the..-stud is again returned .to thestartingposition,lthe momentum-carries the ring 'forwardinQits-rotationalmovement=until stopped by the studin its'innerlposition. 1f, when inthis position, .the stud isagain movedaway'from the pivot theiring isrotated in the reverse .fdiiection and by restoring the. stud-.at .theproper time-the momentum completes .the movement .of the .ring, that.is, a complete oscillating cycle.

.T-he ringlthusoscillates back and-forth inresponse to the outwardand'inwar'd movement .of the .studrelative to .the pivot. [A convenientway of securing this movement is by. apair' o'flevers, one of-wh-ich.formsa handle. andis connected .to thestud and the other forms afinger..grip,fis pivoted .to the firstlever and supports the. pivoto'flthering. 'By moving the levers'towards'and away from each other in astep actionthe ring isoscillated once in. each directionafor each. step,that is, each cycle of -movement of the levels movesthe ring to a newposition, where it remains until again moved by another cycle ofmovementof the levers.

An application of the invention isshown in connection with adisappearing toy whichdisappears into a box and is operated by a ringcontrolled by the levers sotlaat for each operation the figure'is movedout ofthe box to be moved backiagairi bythe next operation of thelevers.

T In the drawings, H is the leverlcomprising'the handle 4whichlsupportslthe stud!!! and [2 is the complementary lever pivoted toHat l3 and operated by a "finger grip at 1'5. "I'he'lever 12 supportsthe pivot IQ of the ring IB and by spring i6 and stops I'l assumes anormal position relative to the lever l2 which brings the pivot l9 andthe stud 2E] relatively close together Within the ring l8. When thefinger grip I5 is moved towards M, the stud 291 is moved away from thepivot 19 and rides along the inner surface a of the ring 68, causing thering to move on the pivot I9 along the are indicated by c to theposition [8' where it is stopped by the opposite side of the ringengaging the stud 20. The ring is provided with an arm 2|, carrying anindicating device 22 which corresponds with the object to be oscillated.22 may be freely rotated on 2| and weighted at 23 so that when the ringl8 moves to the position shown in Fig. 2 the indicating device 22 isrotated by the weight 23. It will be observed from Fig. 2 that thereverse movement corresponds to the movement in Fig. 1 except that thestud 20 engages the opposite side of ring l8 at b to rotate it in theopposite direction.

The operation will be understood from Fig. 3 showing the stud 2B movedaway from the pivot l9 by deflecting the levers a distance correspondingto the diameter of the ring in which the arm 2| is in the verticalposition. If the levers are held in this position, the device is lockedand the arm 2| remains vertical, but if upon reaching this position thelevers are returned to the normal position with the stop members I! inengagement, the ring continues the movement of the initial impulse asfar as the stud 20 will permit.

In Fig. 4 the arrangement is modified to use a disc 24 instead of thering I8. This disc is provided with an arcuate slot 25 located about thecenter which engages the stud 29. When the stud 26 engages the outerportion of the slot d the first impulse is transmitted to the arm 21and, after passing the center, the stud then engages the inner surface eof the slot as it is moved by spring l6, thereby driving the arm for afull stroke in both directions without lost motion.

It should be understood that the ring and the stud engaging the ring areshown in diagrammatic form and would have to be constructed in a mannerbest suited for the work intended. Further, the ring may be made in theform of a cam to vary theimpulse transmitted thereto.

In Fig. the lever I l terminates in the handle 3| and the lever l2terminates in the finger grip 32, the rubber band 33 holds these leversin the closed position. A vertical slot is provided in lever I l at 34and a corresponding slot 35 is provided in lever l2 for the freevertical movement of the wire ring I8. This ring is provided with anextension 36 secured to the figure 31 located in the housing 38 andarranged so that it may pass through the aperture 39 which is normallyclosed by the flaps 42 and 43. A table is provided at 4| with a slot at40 for the movement of member 36. When the figure is moved out of thebox by the operation of 32, it rests on the table 4| as indicated inFig. 6. The next movement of lever 32 oscillates the ring l8 and movesthe figure 3! back into the box through the flaps 42 and 43. Theposition of the ring l8 and the extension 35 is indicated at 36a, Fig.'7, when the figure is on table 4|.

This mechanism is simple, low in cost and very effective for operatingtoys or for utility purposes.

Having thus described my invention, I claim:

2. A mechanical motion comprising a disc having a pivotal support on itsperiphery, and an arcuate slot formed about its center, a stud engagingsaid slot without lost motion and means for moving said stud towards andaway from the pivotal support of said disc to move said disc in onedirection.

3.
